Description

Technical Field

[0001] The utility model relates to the manufacture of cables and conductors, in particular to a traction machine for producing special hard wires. Background Art

[0002] Pullers for specialized hard wire production are widely used in cable and wire manufacturing across a wide range of industries, including aerospace, automotive, energy and power, communications, industrial automation, and building infrastructure. In the manufacture of high-voltage cables, high-temperature automotive wires, fiber-optic composite cables, and wind and nuclear power cables, pullers precisely control speed and tension to ensure the stability and quality of hard wire during processing. Their core function is to adapt to the demands of specialized materials and complex processes, such as processing high-strength, high-temperature-resistant, lightweight, or multi-layered specialty cables.

[0003] Tractors for specialized hard wire production utilize precise tension and speed control, specifically designed for the production of high-strength, high-temperature-resistant wires. Their primary structure comprises a traction system (such as pulleys or tracks), a drive system (servo or variable-frequency motor), a tension control device, a PLC control system, and a high-strength frame structure. The equipment is equipped with cooling and lubrication systems to ensure long-term stable operation. The tractor's core function is to maintain constant tension and speed during the wire production process, preventing breakage, bending, and surface damage. It can accommodate the processing needs of a variety of specialized materials (such as nickel alloys and steel-core aluminum wire) and works in conjunction with wire drawing machines, coating machines, and other equipment to ensure efficient operation of the entire production line.

[0004] However, in the application of existing technologies in traction machines for the production of special hard wires, the ability to guide and straighten wires is relatively limited. Traditional equipment lacks an effective auxiliary guiding mechanism, which may cause the wires to bend or deflect before entering the traction belt, thereby causing surface wear or dimensional deviation problems, affecting product quality. In addition, the existing guide roller design is usually fixed, which makes it difficult to adapt to the production needs of wires of multiple specifications. It has poor versatility and is cumbersome to adjust. In terms of high-temperature material processing, the cooling system often only targets the drive or transmission components inside the equipment, while ignoring the precise cooling of the contact area between the traction belt and the wire. This defect can easily cause the traction belt to overheat and wear, shortening its service life, and increasing the risk of damage to the surface of the wire. Overall, existing equipment that lacks precise guiding and cooling technology is difficult to meet the needs of high-precision, high-temperature, and high-intensity production, limiting its application and efficiency improvement in multiple scenarios.

[0005] In view of the above problems, a traction machine made of special hard wires is proposed to solve the above problems. Utility Model Content

[0006] In order to make up for the above deficiencies, the utility model provides a traction machine for the production of special hard wires, aiming to solve the problems of wire bending deviation, low cooling efficiency and insufficient adaptability.

[0013] As a further description of the above technical solution:

[0014] The latch is inserted into the interior of the fixing hole, and the end of the transverse guide roller is rotatably connected to the interior of the fixing block.

[0015] As a further description of the above technical solution:

[0016] The bottom of the vertical guide roller is rotatably connected to the interior of the sliding block, and the top of the vertical guide roller is slidably connected to the interior of the limiting plate.

[0017] As a further description of the above technical solution:

[0018] The traction mechanism includes two power rollers and a servo motor. Traction belts are installed on the outer sides of the two power rollers, and the output end of the servo motor is fixedly connected to the inside of the power rollers.

[0019] As a further description of the above technical solution:

[0020] The four servo motors are all fixedly connected to the outer side of the partition.

[0021] As a further description of the above technical solution:

[0023] As a further description of the above technical solution:

[0025] The utility model has the following beneficial effects:

[0026] 1. In this utility model, auxiliary guide mechanisms are installed on both sides of the traction machine's traction belt. Controlled by two sets of transverse and vertical guide rollers, the wires are kept straight before entering the traction equipment, preventing bending or deviation. This not only reduces stress on the wires during traction, but also minimizes surface wear and diameter deviation caused by bending. Furthermore, the adjustability of the guide rollers allows them to accommodate wires of varying sizes and hardnesses, enhancing the versatility and flexibility of the equipment, which is particularly important in the production of multi-standard wires. It also improves the stability and processing quality of the entire production line, ensuring greater precision for subsequent processes such as coating and cabling.

[0027] 2. In this utility model, a water pump is installed inside the equipment to circulate coolant around the servo motor, providing efficient heat dissipation for key drive components and ensuring the stability and safety of the equipment during high-speed operation. In addition, the coolant is sprayed onto the contact area between the traction belt and the wire through an atomizing nozzle, providing precise local cooling. This can effectively address the problem of heat accumulation in high-temperature materials during the traction process, prevent wear and performance degradation of the traction belt due to high temperature, and avoid damage to the wire surface due to overheating. This significantly improves the traction equipment's tolerance to high-temperature, high-intensity operating environments, extends the service life of the equipment and traction belt, and meets the high-temperature material processing requirements of special hard wire production.

[0039] Specifically, in this embodiment, a storage cabinet 2 is installed at the lower part of the tractor body 1 for storing some sundries. The auxiliary guide mechanism 4 is located on both sides of the device. The wires must pass through the auxiliary guide mechanism 4 when entering and sending out. Two horizontal guide rollers 403 are installed inside the support block 401, and two vertical guide rollers 407 are installed between the limit plate 408 and the top of the support block 401. A slider 409 is installed at the bottom of the vertical guide roller 407. The slider 409 can slide inside the slide 406 and is adjusted by the elastic force of the outer spring 410.

[0041] Specifically, two traction mechanisms 3 are set on the inner side of the upper part of the traction machine body 1. After the servo motor 303 is started, it can drive the power roller 301 to rotate. The rotation of the two power rollers 301 drives the traction belt 302, and the wires will be pulled by the upper and lower traction belts 302 and sent to the next processing equipment through the auxiliary guiding mechanism 4.

[0042] Reference Figure 5 - Figure 7 A partition 5 is fixedly connected to the interior of the traction machine body 1, and a cooling mechanism 6 is arranged behind the partition 5.

Two atomizing nozzles 605 are also installed inside the cooling annular pipe 604. The atomizing nozzle 605 can spray a small amount of coolant on the inner side of the traction belt 302, effectively cooling the traction belt 302.

[0044] Working Principle: The wires enter the tractor body 1 through the auxiliary guide mechanisms 4 on both sides. The auxiliary guide mechanisms 4 consist of a support block 401, two transverse guide rollers 403, and two vertical guide rollers 407. The transverse guide rollers 403 use a manually adjustable assembly to adjust the position of the fixing holes 402 to accommodate wires of varying diameters. The vertical guide rollers 407 automatically adjust their spacing using two sliders 409 and a spring 410 to ensure the wires remain straight. Once the wires enter, the two traction mechanisms 3 at the top of the tractor body 1 drive the four powered rollers 301 via servo motors 303, thereby driving the upper and lower traction belts 302 to clamp and pull the wires. The cooling mechanism 6, using a pump 601, circulates coolant through the outlet pipe 602 to the cooling annular pipe 604, cooling the four servo motors 303. Simultaneously, two atomizing nozzles 605 within the cooling annular pipe 604 spray coolant onto the inside of the traction belt 302 for localized cooling, protecting the belt 302 and extending the life of the equipment. Finally, the wires are pulled to the next process step.
